Slop Index
The Slop Index
Slop is AI writing that could have come from anywhere: stock phrases, characters who share one voice, details that vanish between sessions, scenes that loop, prices that climb once you care, and art with generator tells. We score each of those from 0 to 100. Lower is better.

What each score means
Each axis has five bands, one per Slop Meter tier. A score has to sit in the band its receipts support.
| Tier | ProseDoes it write like a person? | MemoryDoes it remember you? | CharactersDoes everyone sound the same? | StoryDoes anything happen? | PricingDoes it charge you for caring? | ArtDoes the art look like a person made it? |
|---|---|---|---|---|---|---|
| Artisanal0-15 | Specific, varied writing. Stock phrases are rare, and people write or edit what you read. | Remembers specific events across sessions, by design. | Distinct, consistent voices written or edited by people. | Authored plots with stakes, branches and endings. | Free or one flat price, with no limit that interrupts a scene. | Hand-drawn or finished art, consistent across every image. No generator tells. |
| Home-cooked16-35 | Mostly specific, with a few repeated habits. | Long-term recall holds for the details that matter, with occasional misses. | Consistent characters, with some sameness between them. | Structured scenarios or quests that move forward. | Clear prices shown before you pay, and limits you can predict. | Generated or assisted art that someone fixed and finished: consistent faces, clean hands, deliberate style. |
| Microwaved36-60 | Stock phrasing in most replies. Readable, but you have seen it before. | Remembers within a session; long-term recall is patchy or up to you. | Voices blur together, and personality depends on the character card. | A plot exists if you drive it; the app follows more than it leads. | Features you will want sit behind a subscription or a currency, with caps you will notice. | Clearly generated, with the default gloss and occasional errors, but characters stay recognizable. |
| Cafeteria61-80 | A cliche in nearly every reply: whispers, smirks, racing hearts. | Forgets between sessions unless you maintain notes yourself. | Most characters share one default voice. | Scenes loop and stall without heavy steering. | Caps or paywalls that land mid-conversation, or a currency that hides the real price. | Frequent tells: broken hands or anatomy, garbled text, the same waxy face, or a character who looks different in every picture. |
| Pure Slop81-100 | Wall-to-wall stock phrases and stock names. Any two replies could swap places. | No memory past the current chat, or it confidently remembers things that never happened. | Every character is the same assistant in a different costume. | Nothing happens unless you write it. | Costs climb as you get attached, or cancelling is a fight. | Raw generator output shipped as final: melted features, gibberish text, and no two images of a character match. |
